The agencies are proposing several options: adding one or two general purpose lanes in each direction, adding one general purpose lane and one toll lane in each direction or doing nothing.

The Costa Mesa City Council passed a resolution against the option that includes the toll lanes. It’s concerned about construction noise and a bridge that would be demolished. Costa Mesa supports the idea of adding general purpose lanes.

Ted Nguyen with the transportation agency says the public comment period has now been extended to July 17.

“We wanted to provide a maximum amount of opportunities for the public to provide their feedback with us," Nguyen said.
